Signal is received to be adjusted（For example, filtering, amplification and down coversion）, adjusted signal is digitized to provide sampling,
And sampling is further processed to provide corresponding " reception " symbol stream.
Then, RX data processors 260 are received and handled from N based on specific receiver treatment technologyRIt is individual to receive
The N of machine 254RThe symbol stream of individual reception, to provide NTIndividual " after testing " symbol stream.Then, 260 pairs of RX data processors are each
Symbol stream after testing is demodulated, deinterleaves and decoded, to recover the business datum of data flow.By RX data processors
260 processing carried out and the processing performed by the TX MIMO processors 220 and TX data processors 214 of transmitter system 210
Conversely.
Processor 270 periodically determines which pre-coding matrix used.Processor 270 formation include matrix index portion with
The reverse link message of rank value part, and processor 270 can mutually operate with memory 272 and communicate.
Reverse link message can include the various types of information related to the data flow of communication link and/or reception.
Then, the reverse link message is handled by TX data processors 238, is modulated by modulator 280, by emitter 254a
It is adjusted to 254r, and is sent back to transmitter system 210, wherein, TX data processors 238 are also received from data source 236
The business datum of multiple data flows.
At transmitter system 210, the modulated signal from receiver system 250 is received by antenna 224, by
Receiver 222 is adjusted, and is demodulated by demodulator 240, and is handled by RX data processors 242, with extract by
The reverse link message that receiver system 250 is sent.Then, processor 230 determines which pre-coding matrix to determine ripple using
Beam shaping weight, then the message to the extraction handle.

Such as the frequency range of frequency band or frequency channels or the like.
According to the one or more aspects of embodiment described herein, there is provided for network code and being applied to
The technology of P2P communications.In P2P communication systems, the user of mobile entity can be communicated directly with one another.Additionally or
Alternatively, they can also pass through third party entity to person（Such as, for example, base station（Such as eNB）Or another mobile entity）That
Communicated between this.For example, the first user can send first information A to third party, and the third party then can be to
Second user sends first information A.Similarly, second user can send the second information B, and the third party to third party
Second information B can be then sent to the first user.
In specified communication system, first information A can be encoded（For example, by using turbo codes, convolution
Code and/or other encoding schemes）, modulation and send.Cataloged procedure of the cataloged procedure independently of the second information B.For example, first
Information A+ CRCs（CRC）→ Turbo codings → scrambling → modulation → RF transmission.
Third party（For example, the 3rd user）First information A and the second information B can be combined into the 3rd/encoded letter
C is ceased, and the 3rd information C can be sent to the first user and second user simultaneously.First user and second user can make
Use existing information（For example, first information A or the second information B）Together with the 3rd/encoded/the information C combined comes to packet
Decoded.For example, the first user can use first information A（That is, the first user wants the information sent to second user）,
And second user can use the second information B（That is, second user wants the information sent to the first user）.
There are a variety of methods and first information A and the second information B are combined into the 3rd information C.In one approach, can be with
XOR is performed to first information A and/or the second information B information bit before the coding（XOR）Computing etc..In another method
In, XOR can be performed to first information A and/or the second information B coded bits before modulation（XOR）Computing etc..
In another method, the operation of linear-type can be performed to first information A and/or the second information B to produce the 3rd/it is encoded
Information C.
In related fields, third party entity should be sent or offer to the first and second mobile entities with signal：On
How first and second mobile entities are should be to the 3rd/encoded information C decode/information used, and third party
Entity applies this extra process for which packet.This mode is used, the first and second mobile entities will know realization respectively
Which type of extra process recovers the second information B and first information A.
In one embodiment of P2P communication systems, two equity points can use third party entity to come between them
Transmit data or signaling.For example, the first and second users or mobile entity can be specified LTE UE.3rd user or the 3rd
Fang Shiti can be eNB or other network entities.First and second users can be communicated with third party entity, to exchange
Data/information.For example, when eNB sends the packet for the one or more processing being performed in following processing, it can make
Use downlink control signal（For example, physical downlink control channel（PDCCH））Or the signaling of layer 3 carries extra letter
Breath：（a）Before the coding, to having carried out XOR by the information bit of target of the first user and second user（XOR）（When for
When first user is identical with the quantity of the information bit of second user, XOR can be performed to each bit（XOR）Computing；When
When the quantity is different, XOR can be performed to the subset of these bits（XOR）Computing etc.）；（b）Before modulation, use first
The coded-bit of family and second user carries out XOR（XOR）Computing；Or（c）Other processing, so that resulting packet
It is the function of the information bit of the first user and second user.
In related fields, the 3rd resulting/encoded information C can include：For from the 3rd/encoded information
First information A and/or the second information B key is extracted in C.For the signaling of layer 3（Wireless heterogeneous networks（RRC）Signaling is wide
Broadcast）, the first and second users can use the key related to known system information determine eNB to which packet perform
Process as described above/cataloged procedure.For example, the key can include the 3rd information C header.
For the PDCCH signaling of layer 1, PDCCH payload portions, CRC masks in PDCCH and/or given/
The bit mode of definition can include or indicate whether eNB is described above to being performed relative to the PDCCH PDSCH authorized
Processing/cataloged procedure.The key can also include：On first information A and the information of the second information B size（Such as, example
Such as, when respective information is of different sizes）.For example, the transmission block that information A and/or information B size can include in LTE is big
It is small（TBS）.
From the perspective of UE, once UE receives one performed to PDSCH in processing/coding described above
During individual or multiple signaling, UE can be with the information being previously sent using it and currently received PDSCH, to recover other UE purports
In the information being sent to via eNB.For example, the first mobile entity of the first user can be used（a）It is previously sent
One information A and（b）Currently received PDSCH or the 3rd/encoded information C, sends out to recover the second mobile entity via eNB
The the second information B sent.
In other related aspect, the medium access control in PDSCH can also be passed through（MAC）Protocol Data Unit
（PDU）Control unit transmits to perform signal.Which up-link MAC PDU emitters can also should use with signal transmission
To be decoded to contemporary downlink MAC PDU.The signaling can be embedded in effective load of downlink MAC PDU header
In lotus etc..Processing described above/encode and bel not applied to the MAC PDU headers.Emitter can match somebody with somebody to user
It is right, so that when the execution processing/coding（For example, XOR（XOR）Computing etc.）When, the TBS from those users is
Matching.Or, if TBS is different, shorter transmission block can be filled, to believe first information A and second
The respective TBS of breath B both matches.
Understood as shown in the figure with example system described herein after, can be more with reference to each flow chart
